STRUCT EDAC_SCRUB_OPS(9)

💖 struct edac_scrub_ops(9) 💖

okay bestie, welcome to the Kernel API Manual — this page is giving “scrub device ops, but make it optional” energy, because literally every element here is optional. No cap. 🫶

✨ NAME ✨

struct edac_scrub_ops — scrub device operations, and bestie, all elements are optional. Every single one. The whole vibe is “use what you need, skip what you don’t.” 💅

🦋 SYNOPSIS 🦋

here’s the whole struct, copied with love and zero edits:

       struct edac_scrub_ops {
           int (*read_addr)(struct device *dev, void *drv_data, u64 *base);
           int (*read_size)(struct device *dev, void *drv_data, u64 *size);
           int (*write_addr)(struct device *dev, void *drv_data, u64 base);
           int (*write_size)(struct device *dev, void *drv_data, u64 size);
           int (*get_enabled_bg)(struct device *dev, void *drv_data, bool
       *enable);
           int (*set_enabled_bg)(struct device *dev, void *drv_data, bool
       enable);
           int (*get_min_cycle)(struct device *dev, void *drv_data,  u32 *min);
           int (*get_max_cycle)(struct device *dev, void *drv_data,  u32 *max);
           int (*get_cycle_duration)(struct device *dev, void *drv_data, u32
       *cycle);
           int (*set_cycle_duration)(struct device *dev, void *drv_data, u32
       cycle);
        };

🌸 Members 🌸

• read_addr — reads the base address of the scrubbing range. iconic little address reader. 📍
• read_size — reads the offset of the scrubbing range. yes, offset, bestie. 📏
• write_addr — sets the base address of the scrubbing range. write it down, slay. ✍️
• write_size — sets the offset of the scrubbing range. offset but make it official. 🎀
• get_enabled_bg — checks if it’s currently performing a background scrub. bg-scrub status check, iykyk. 👀
• set_enabled_bg — starts or stops a bg-scrub. on or off, no in-between. 🔥
• get_min_cycle — gets the minimum supported scrub cycle duration in seconds. seconds, periodt. ⏱️
• get_max_cycle — gets the maximum supported scrub cycle duration in seconds. also seconds, also slay. ⏲️
• get_cycle_duration — gets the current scrub cycle duration in seconds. current duration check ✨
• set_cycle_duration — sets the current scrub cycle duration in seconds. new duration, who dis 💫

bestie reminder: all elements are optional. the struct is not gonna force you into anything. 🙈
